I'm a native Portuguese speaker. While playing in the Reddit settings page, i noticed that my language was not fully translated. So i got curious and decided to try and help the process. I went ahead and translated a few strings.

I have done something similar in the past (a couple strings in Minecraft and in Steam, neither of them used this platform)

My transifex nick is Ricardo1991.

I can also do reviewing. There is a queue of 1500+ strings that need to be reviewed. Seeing that PT(BR) is fully translated and PT(PT) is not kind of makes me sad.
